Updating Android to the Latest Version
-
Once you have updated, you cannot return your tablet device to an older version of Android. Updating requires the remaining battery level to be at 50% or greater and use of the AC adapter. Your tablet device may no longer turn on if the battery is depleted while updating.
-
The data stored on the internal storage (memory space in your tablet device) will not be erased by updating.
-
There must be enough free space on the internal storage to download the update files when updating.
-
Some applications may not be compatible with the updated version of Android, and they may no longer run after updating.
-
Be sure to check the Android version that each application is compatible with before updating.
-
Updating may take longer if you connect to the Internet using the mobile communications function. In addition, large data charges may be incurred depending on the service you subscribe to.
